AbstractThe compound 5-amino-2-mercapto-1,3,4-thiadiazole (AMT) is utilized in the conservation of archaeological and artistic bronze artifacts, for their protection and for the removal of corrosion products. Many authors have discussed the utility and efficacy of this, but few have studied the products resulting from the reaction of AMT with bronze or with the corrosion products of bronze; this leaves the restorer with many doubts concerning the acceptability of this method. This paper discusses the study of products obtained from the reaction of AMT with synthesized corrosion products of bronze (malachite, paratacamite and brochantite) and with the commercial bronze alloy TM 23 (Cu 72%, Pb 15%, Zn 8% and Sn 5%). It was found that the film obtained from the direct reaction of AMT with the bronze alloy can be AMT itself, or the metallic complex Cu(C2H2N3S2)2·H2O if AMT is applied in a solution of an oxidizing acid. These results are expected to be of value to conservation scientists and restorers/ conservators concerned with the use of AMT for the conservation of bronze artifacts. 相似文献

金文档案是载有原始凭证价值的青铜器铭文,由于其形成时间久远,且长期埋藏于复杂、潮湿的地下环境,致使这些金文档案出现不同程度老化;出土后如不及时采取有效的保护措施,金文档案老化速度会加快,严重威胁金文档案寿命. 相似文献

中国古代青铜器源远流长,萌芽于原始社会后期,夏代初步发展,商周鼎盛,春秋战国繁荣,秦汉则变革、中兴,两晋南北朝至隋唐走向衰落。青铜器在其漫长的发展过程中曾有过一种特殊用途,即作为金文档案的载体材料而存在,它作为历史上档案载体材料的一种,对金文档案的出现、发展、消亡产生了举足轻重的影响。 相似文献

ABSTRACTTwo Spiritelli attributed to Donatello have been extensively studied from a technical point of view, including X-radiography, alloy analysis, characterization of the core, and visual observations on the interior and exterior of the statues. The results of this technical study reveal how the two statues were cast and document the artist’s technical choices. These new insights offer additional information to address questions regarding their attribution, production context, and conservation history. First, the technical study confirmed that the statues were made by the same workshop and argues against the prior proposal of different attributions for the two figures. Second, the results strongly suggest that the statues have never been separated since they were taken off Luca Della Robbia’s Cantoria. Finally, study of the two Spiritelli offers further evidence of the heterogeneity and ingeniousness of Donatellos bronze artistic production, and contributes to the ongoing debate whether the artist himself was involved in the technical aspects of his sculpture. 相似文献

Artistic patination is a traditional colouring technique for metal sculpture, employed by artists in ancient and modern times for aesthetic purposes. Today, knowledge of the artistic value and the chemistry of this superficial chromatic layer, called ‘artistic patina’, can be successfully acquired through a close collaboration between living artists, foundry artisans, and scientists. Starting from several interviews with the Italian artist Nado Canuti and foundry artisans, specific information was gathered about patination methods and the artist’s attitude towards materials restoration. Afterwards, the patinas most used by Canuti were reproduced to study their nature before any ageing or degradation. Their chromatic values, morphologies, and compositions were studied employing a range of techniques such as colour measurements, scanning electron microscopy with energy dispersive X-ray spectroscopy, and micro-Raman spectroscopy. The collected data revealed the formation of main compounds (cuprite, cassiterite, rouaite, chalcocite, isocubanite, and ferroxyhite) and additional compounds (atacamite and CN-containing compound). The scientific results, as well as the artist’s statements concerning the patinas’ significance, maintenance, and conservation, will contribute towards the future care and preservation of Canuti’s sculptures. 相似文献
